Is it possible to differentiate ?
I can't work out what I would do with to get it to differentiate. Any help?

[Slumpy]

i is a constant.

dont think you can, as minus square roots can't be changed into an indices? I think :P

[bananarama2]

It's a constant?

[Occams Chainsaw]

So far I have got that


so now I need to differentiate in respects to right?

as Slumpy said, i is a constant. However functions of complex variables can be differentiated. This is done by differentiation the real and imaginary parts seperately and using the Cauchy Riemann equations, see: http://en.wikipedia.org/wiki/Cauchy%...mann_equations (its unlikely that page will be understandable if you havent taken at least undergrad real analysis, but you can google for 'complex differentiation' and try to find something more elementary)

Does make sense?

You can differentiate complex variables though.

for example : http://www.ams.org/bookstore/pspdf/mbk-49-prev.pdf (although this still presupposes a basic background in analysis)

Ignoring the fact I already told you i is a constant, what are you trying to do here? You've gone from the definition of i to a chain rule version of dy/dx, without having defined a y or x. Then your next line is a bit weird.

Your right.

I have just started c1 maths in college but I have been playing around with further maths and certain constants such as i and e and I guess my lack of understanding showed there Thanks for your help anyway.
